Abstract
A converting controller, adapted to control a converting circuit to convert an electric power from an input power source, is provided. The controller comprises a duty cycle control unit, a protection enabling control unit and a protection unit. The duty cycle control unit controls the converting circuit according to a feedback signal for converting the electric power from the input power. The protection enabling control unit outputs protection enabling signals according to time results of a timing circuit. The protection unit detects the converting circuit and generates a protection signal when any circuit error is determined, so as to stop the duty cycle control unit, wherein the protection unit has a plurality of protection functions and enables the protection functions with respect to the protection enabling signals, respectively.
